Answer:
[tex]7.8 * 10^{10}[/tex] is scientific notation of 78 billion
Step-by-step explanation:
For scientific notation , follow the following notation:
[tex]a * 10^{b}[/tex] -------->(equation 1)
Let, [tex]a^{'} = 78 billion[/tex]
[tex]a^{'} = 78000000000[/tex]
[tex]a^{'} = 78000000000.0[/tex]
In standard form
[tex]a = 7.8000000000[/tex]
or
[tex]a = 7.8[/tex]
As decimal point move 10 places from right to left, therefore
b = 10
Put the value of 'a' and 'b' in (equation 1)
[tex]7.8 * 10^{10}[/tex] is scientific notation of 78 billion
